An integrated method of production planning and scheduling in an intelligent machining workshop

Abstract

The invention discloses an integrated method for production planning and scheduling of an intelligent processing workshop, which belongs to the application field of automation technology. The method of the invention includes the following steps: system modeling; data preparation; order preparation; production planning and scheduling; virtual processing; dynamic monitoring; dynamic scheduling; plan revision; rolling optimization. Through the integration of production planning and scheduling supported by the cyber-physical system of the intelligent workshop, the closed loop of "production planning - production scheduling - production status information" in the dynamic workshop environment is realized, and the existing production planning and scheduling methods are difficult to respond to the environment in time ( market) changes and various dynamic events on the workshop site.

Description

technical field [0001] The invention relates to an integrated method for production planning and scheduling in an intelligent machining workshop, and belongs to the technical field of automation. Background technique [0002] Production planning and scheduling has always been the core content of enterprise production management optimization. With the development of society and changes in market demand, multi-variety, small-batch, and order-oriented production has become the main production mode of most machining enterprises. The dynamics and uncertainty of the production system have been greatly improved, further increasing production planning and scheduling. difficulty. In the prior art, production planning and scheduling are carried out in a hierarchical manner, that is, the planning layer gives a plan, and the scheduling layer then schedules production according to the plan. In order to meet the scheduling constraints or possible random changes, the production plan must...
